Pavilion dv9500z fan help!!

i have an hp pavilion dv9500z with an amd processor and windows vista home premium 32 bit. my fan always seems to be running faster then it should, or at least its alot louder then it used to be. i need help on why it might be so loud..thanks

 

The fan is continually running because something you are running intentionally or non intentionally is using some cpu power.
Open task manager, and see what the cpu usage is.
AT idle the cpu should not be running more than 5-10% load.
If it is running higher than that, you need to disable some background processes, to free up the cpu cycles.
You can do this by going to the run command. Than type in MSCONFIG
than go to the startup and services tabs and shut off processes and applications which you do not use. This will free up cpu cycles, memory and harddrive use, resulting in a faster and cooler running laptop.


You can also try undervolting, Flipfire made a nice guide here: the Undervolting Guide
Undervolting does not decrease system performance, it just makes the processor more efficient.

Usually anytime you've got a fan working overtime it means either a vent is clogged, your system is dirty, the system is working harder than it needs to be in order to keep the system cool, or it's working harder because it's dirty and has too many processes going at the same time. Of course having a notebook on a surface that prevents air from being pulled into the intake causes overheating as well. Or it could just be a bad fan.

Assuming you've already checked and cleaned the intakes and exhaust, check to see how many processes you've got running in the background. You didn't mention if you have one or two internal drives - if you have a minimum RAM configuration (1gb) and have only one drive, it's a surefire way to make a system work harder than it should as the system uses the drive to make up for the lack of RAM to keep many processes running.

First thing you need to do is to establish baseline internal temperatures for your system components - you can do that by installing and running HWMonitor http://tinyurl.com/df5ax . That will show you what your internal temps are - record the values for key components and especially note the CPU and GPU temperatures.

You should also open your Task Manager and go to the Performance tab to see just how hard your system is working. If your consistently seeing high CPU usage, you've got too much stuff working the system. Use your Startup Manager to reduce some of the processes working, and then check your temps again.

If your system is running within normal temperature limits, as I said before it can always be as simple as a bad or dirty fan. Try and locate which fan is causing the problem - if it's not apparent by sound, use your finger to locate the area as it should be causing some vibration if it's noisy enough to be heard. You can always use a mechanic's stethoscope or equivalent (long, thin dowel rod held to the ear) to narrow down the location, then check the system manual to see which fan it is and how accessible it is if you're comfortable working on your own system. Fans are easy to check to see if they're bad or not - when you spin it by hand, it should rotate freely and without any resistance. If it's clogged with dust, blow it out first before spinning it. If it stops rotating after a 2 or 3 rotations, the bearings are gone and you need to replace it, also a simple enough procedure if you're comfortable working on your own system.
